OZ Lifting Products CompOZite Davit Crane OM - Manual (Page 11)

Loads are normally lifted by use of the manual winch that is supplied on the crane. In some instances (e.g.
to lift over a parapet), the ratchet binder will be used to adjust the angle of the boom and lift the load further.
The load should then be removed from the crane using the manual winch. The ratchet binder should not be
used to completely remove the load from the crane. This could cause the manual winch to become difficult
to operate due to the brakes being set for the higher line tension.
NOTE: The boom of the crane should never be lowered below horizontal while manipulating a load. The
boom should only be lowered for storage purposes.
This CompOZite Davit Crane has a main structure made from an advanced composite material. At
maximum rated load, this advanced composite material may exhibit some very slight deflection. The crane
will return to its original position upon releasing the load. At no time should the crane emit any abnormal
noises during use. Any abnormal sounds are cause for removal of load and inspection. There are
multiple sources for abnormal noises including, but not limited to:
• If the cable is not spooled neatly, under tension, when load is applied.
• If the crane is severely overloaded.
• If the crane has suffered severe damage from abuse and/or mishandling.
NOTE: This list is not exhaustive and does not cover all possibilities.
Cleaning & Lubricating the Crane
The CompOZite Davit Crane should be periodically cleaned to preserve its appearance and to prevent
corrosion. The CompOZite Davit Crane will last longer and perform better when it is kept clean and lubricated.
NOTE: No solvents should be used on any parts of the CompOZite Davit Crane for cleaning or any other purpose.
Instructions:
1. Wipe the surfaces of the crane with a wet cloth. Detergents are not necessary.
2. The steel surfaces should have a light film of oil applied to them to prevent corrosion.
It is not necessary to oil the composite components as they are impervious to corrosion from moisture.
NOTE: No lubricants of any kind should be applied to the brakes in the winch. If the brake pads get
contaminated with oil, they may slip.
3. Remove any excess oil with a clean cloth.
4. Lubricate the bushing in the load sheave with a light coat of grease.
5. Lubricate the shaft bearing surfaces on the winch with a light coat of grease, taking care not to get any
oil or grease on the brake pads of the winch.
Inspecting the Crane
In order to maintain quality operation of the product, a regular inspection schedule should be followed by
each operator. All inspections should be reported and maintained in a dated record log. These records
should be available to all personnel involved with the product and should be made available to OZ Lifting
Products LLC ® when a warranty issue is in question.
